Maybe a SMP issue ? Does this problem also happen without CONFIG_SMP ?

No no, what I mean by 'manually fixed kernel_page_tables' is that I fixed the
file you attached so that it has the same values as what it would have had with
the patch applied.

--- Comment #9 from Erhard F. (erhar...@mailbox.org) ---
I can apply the patch but how do I apply the manually fixed kernel_page_tables?
Not quite sure how to proceed.
